Gorgeous model Sarah Shevon is worried about all the intense anal sex she's been having, so she schedules an emergency exam with Dr. Mark Wood. Upon lubricating his glove and probing her tender anal ring, he stretches open her sphincter with a metal speculum. The dirty doc pushes a huge phallic instrument inside, pumping the inflatable shaft to fill Sarah's rectum. When Mark's thick erection explores her juicy cunt and elastic butthole, the luscious patient shows appreciation by sucking his prick clean as her anus blooms in a glistening prolapse. Sarah receives a messy mouthful of sperm.
